Four-Channel Network Video Server
Eric Gagnon
Eric
recently built a video surveillance system to monitor
his property when he isn’t home. He saved a lot
of money by incorporating a four-channel network
video server rather than expensive IP cameras. The
video server, which Internet-enables four conventional
NTSC cameras, provides a standard Ethernet network
interface. p. 16

Read
it now!
by Ingo Cyliax
Ingo’s Wi-Fi Sunlogger is a solar-powered data collector that
records sunlight exposure. This RCM3400-based
device is the perfect tool to have on hand
when scouting out sites for solar panel installation.

Math
Coprocessor for Robotics Applications
Daniel
Ramirez
Need
more processing horsepower for your robot? This
design provides additional functionality to microcontrollers
that don’t support floating-point math and to those
that are too bogged down with other functions. p.

Build
a VGA Monitor Controller
Enoch
Hwang
Enoch
built a VGA monitor controller with just two 10-bit
binary up counters, four SR flip-flops, and 11 AND
gates. The result is an impressive solution for
displays. p. 38

Fast
Ethernet and small microcontrollers do not mix,
or so they say. In this article, Eddie shows you
how to add full-speed, 100-Mbps Ethernet to an embedded
system. Read on to learn about the supporting hardware
that will help you get the job done. p. 44

Stack Solution
A Detailed Look at the CMX-MicroNet
Fred
Eady
If you need more than a minimal TCP/IP stack for
your next application, consider using the CMX-MicroNet,
which is a stack designed for microcontrollers that
have small amounts of data and program memory. This
month, Fred describes the CMX-MicroNet’s behavior.

Security for Small Systems
Jan
Axelson
Nervous
that someone might tamper with your embedded system?
It’s a common concern, but not too many designers
have the know-how to secure a small system. In this
article, Jan walks you through the process of protecting
a system’s code and data. p. 62

DMX
Jeff
Bachiochi
Several months ago, Jeff interfaced a DMX receiver
to a water fountain system. He used a commercial
serial DMX converter for that project. This month,
he describes how he updated the device with a C8051F320-based
USB interface. p. 70

SILICON
UPDATE
Easy to be Soft
Tom Cantrell
Although FPGA-based processors won’t ever completely
replace dedicated processor chips, the FPGA soft-core
option is becoming increasingly attractive to designers.
In this column, Tom examines the soft core concept
by focusing on Altera’s new chips and the Nios II
core. p. 78
